The owls main part of its diet is the vole. After it's [the meat] eaten it gets stored in a special stumick because it is not able to be dijested. then it gets regurgitated. To find out what my owl ate I had to carfuly disect it. A vole is an organism that is the most oftenly found in an owl pellet. What I found was the vole in my owl pellet. It's habitat is a field, a plain or some place with lots of grass and open space. A biospere is all of the economy systems together to make my animals ginormous habitat. If the voles populashon died out the owls would have to find a knew food. The ecosystem is where the apexpredator, barn owl, lives.
